California is the poster child for solar energy: in 2016, 13% of the state’s power came from solar sources. According to the Solar Energy Industries Association, California is in the lead for the cumulative amount of solar electric capacity installed in 2016.
In fact, the California is generating so much solar energy that it is resorting to paying other states to take the excess electricity in order to prevent overloading power lines. According to the Los Angeles Times, Arizona residents have already saved millions in 2017 thanks to California’s contribution.
The state, which produced little to no solar energy just 15 years ago, has made strides — it single-handedly has nearly half of the country’s solar electricity generating capacity.
According to the U.S. Energy Information Administration, California reached a milestone: for a few hours, more than half the state’s power needs were sourced from solar energy. This put wholesale energy prices in the negative. Read more. (6/22/17, 12:15 PM)
while that shadow will produce a once-in-a-lifetime view for millions
of Americans from coast-to-coast it will also wreak just a little bit of
havoc on clean energy in California.
the eclipse, northern California will see 76% of the sun’s rays blocked
by the moon, while southern California will see 62% of the sun’s rays
blocked, according to Cal Eclipse.
the eclipse, the site explained, solar power generation in the state
is expected to go from 64% to 83% capacity at the start of the eclipse
to 15% to 37% capacity at its height around 10:22 a.m. and then return
to normal capacity once it is over.
However, during the eclipse, Bloomberg
noted, more than 9,000 megawatts of solar power may go down across the
country, which is the equivalent of about nine nuclear reactors and is
enough to generate power for about 7 million homes. Steven Greenlee,
spokesman for California’s grid operator, told Bloomberg that the state will need to fill a gap of about 6,008 megawatts.
to help out solar energy consumers during the height of the eclipse the
California Public Utilities Commission is asking all Californians to do
one simple thing: Turn off their lights. Read more (7/25/17)
While access to clean drinking water remains an issue in many parts of the world, there’s no shortage of water on the planet: 97%
of Earth’s water can be found in our oceans.
Turning the ocean’s
saltwater into freshwater is generally an elaborate process that
requires a lot of energy, but a team of scientists at Rice University’s
Center for Nanotechnology Enabled Water Treatment (NEWT) have created a
new method using nothing but sunlight.
thanks to researchers at Rice University, an off-grid desalination
technology is available requiring only solar energy.
Scientists design solar cell that captures nearly all energy of solar spectrum
A George Washington University researcher helped design and construct a prototype for a new solar cell that integrates multiple cells stacked into a single device capable of capturing nearly all of the energy in the solar spectrum.
The new design, which converts direct sunlight to electricity with 44.5 percent efficiency, has the potential to become the most efficient solar cell in the world.
The approach is different from the solar panels commonly seen on rooftops or in fields. The new device uses concentrator photovoltaic (CPV) panels that use lenses to concentrate sunlight onto tiny, micro-scale solar cells. Because of their small size – less than one millimeter square – solar cells that utilize more sophisticated materials can be developed cost effectively.
